    <p>I was trying to create a countdown timer from <a href="http://helloandroidworld.com/2010/02/how-to-create-a-simple-android-countdown-timer/" rel="noreferrer">http://helloandroidworld.com/2010/02/how-to-create-a-simple-android-countdown-timer/</a> but I cannot get it to work with the format I want 00:00:00 as described in the article. The timer will start and allow me to pause it and it will run for two minutes but you cannot see it running. If you pause it you can see how much time is remaining but you I cannot get it to work. Without the formatting it works fine and counts down. Does anyone have this working or know of how to fix it? I have been searching around and cannot find anything covering a countdown timer like this with formatting. Any help would be appreciated.</p> <pre><code> TextView timeDisplay; MyCount counter; int state = 0; int length = 120000; long startTime = 0; long currentTime = 0; long timeElapsed = 0; long timeRemaining = 0; long prevTimeRemaining = 0; Button control; public String formatTime(long millis) { String output = "00:00:00"; long seconds = millis / 1000; long minutes = seconds / 60; long hours = minutes / 60; seconds = seconds % 60; minutes = minutes % 60; hours = hours % 60; String secondsD = String.valueOf(seconds); String minutesD = String.valueOf(minutes); String hoursD = String.valueOf(hours); if (seconds &lt; 10) secondsD = "0" + seconds; if (minutes &lt; 10) minutesD = "0" + minutes; if (hours &lt; 10) hoursD = "0" + hours; output = hoursD + " : " + minutesD + " : " + secondsD; return output; } public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.countdown); timeDisplay = (TextView) findViewById(R.id.timer); control = (Button) findViewById(R.id.control); counter = new MyCount (length, 1000); } public void control(View view) { switch (state) { case 0: startTime = System.currentTimeMillis(); counter.start(); control.setText(R.string.pause); state = 1; break; case 1: // pause currentTime = System.currentTimeMillis(); timeElapsed = currentTime - startTime; if (prevTimeRemaining == 0) timeRemaining = length - timeElapsed; else timeRemaining = prevTimeRemaining - timeElapsed; counter.cancel(); timeDisplay.setText("" + formatTime(timeRemaining)); control.setText(R.string.resume); prevTimeRemaining = timeRemaining; // resume counter = new MyCount(timeRemaining, 1000); state = 0; break; case 2: prevTimeRemaining = 0; counter = new MyCount(length, 1000); control.setText(R.string.start); timeDisplay.setText(R.string.timer); state = 0; } } public class MyCount extends CountDownTimer { public MyCount(long millisInFuture, long countDownInterval) { super(millisInFuture, countDownInterval); } public void onFinish() { timeDisplay.setText("done!"); state = 2; control.setText(R.string.restart); } public void onTick (long millisUntilFinished) { timeDisplay.setText ("Left: " + formatTime(timeRemaining)); } } } </code></pre>

    1. COI got it working. Originally timeDisplay.setText("Left: " + formatTime(timeRemaining)); was timeDisplay.setText("Left: " + millisUntilFinished / 100); and I had tried putting formatTime in front of millisUntilFinished with no success but I tried without the / 100 and it works

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
